No credits are given for the courses. You can take as many as you wish and learn as much as you want to.
On each lecture page there are course details and licensing information (mostly Creative Commons), any related resources such a syllabus, and a fun "dim the lights" feature that blacks out everything but the video.

200 Free Outstanding Online Classes

Take classes online from Yale, MIT, Tufts and other respected institutions for free.
UPDATE: Some of the schools have moved the pages for some of the courses, and the OEDb hasn't updated them on their site yet.
I checked every link listed. The majority still point to the proper course.
Some have moved and provide a link to the new page. The links all led to the the new URL of the same class.
Some have error messages. In the case of error messages, check the home page of the University's Open Course section.
I've listed the links to each University's Open Course site. They have the current class listings.
Some of the links (all at Utah State University) wanted a name and a password. If you run across one of those, check the the Open Course home page. END UPDATE
The Online Education Database has put together 200 online classes from these and other institutions.
You can take as many as you like that interest you - there seems to be no limit and I couldn't find any strings attached in any of the material I've looked at.
Topics cover a very wide range - everything from Natural Science to Law and Politics.
If you want to learn three-dimensional modeling and animation using the Open Source software Blender, there's a course for that.

Introduction
This is a listing of 260 sites that legally offer free books (eBooks) for download or for online viewing.
Some time ago I went looking for some free eBooks and was surprised to find that there are many resources for this.  I decided to put together this list of sites that offer free eBooks as a reference.  Since there are so many, I was not able to check each one out thoroughly.  So comments from you on any of these sites would be appreciated and added to the comments in the article. 

I have tried to make certain that all of the eBooks at these sites are legally available for viewing/downloading.  However, it is possible that I have made a mistake.  If you suspect any of these sites of illegally offering copyrighted materials.Then please let me know

Putting this together was exhausting, but the list is not exhaustive, so I encourage you to post any sites that you know of that are not listed here.

How to Disable Internet Explorer

0 comments
There's no doubt that Internet Explorer has been a prime target of attack for spyware merchants and other ill-intentioned goons. That's why many folks have turned to alternate browsers for their web surfing.

If you are using another browser and don't use Internet Explorer anymore, there's a case to be made that you should remove it from your system. It is, after all, a potential security threat so, if you don't need it, why not get rid of it?

Except, getting rid of IE is not that easy. In fact, with later versions of Windows there's no satisfactory way of removing it completely without risking crippling Windows itself.

8 tweeks to make Firefox ridiculously fast

Friday, May 28, 2010 0 comments
Firefox has been outperforming IE in every department for years, and version 3 is speedier than ever.

But tweak the right settings and you could make it faster still, more than doubling your speed in some situations, all for about five minutes work and for the cost of precisely nothing at all. Here's what you need to do.

1. Enable pipelining
Browsers are normally very polite, sending a request to a server then waiting for a response before continuing. Pipelining is a more aggressive technique that lets them send multiple requests before any responses are received, often reducing page download times. To enable it, type about:config in the address bar, double-click network.http.pipelining and network.http.proxy.pipelining so their values are set to true, then double-click network.http.pipelining.maxrequests and set this to 8.

20 Things the Average Person Doesn’t Know About Windows XP

1 comments
1. It boasts how long it can stay up. Go to the Command Prompt in the Accessories menu from the All Programs start button option, and then type ’systeminfo’. The computer will produce a lot of useful info, including the uptime. If you want to keep these, type ’systeminfo > info.txt’. This creates a file called info.txt you can look at later with Notepad. (Professional Edition only).

2. You can delete files immediately, without having them move to the Recycle Bin first. Go to the Start menu, select Run… and type ‘gpedit.msc’; then select User Configuration, Administrative Templates, Windows Components, Windows Explorer and find the Do not move deleted files to the Recycle Bin setting. Set it. Poking around in gpedit will reveal a great many interface and system options, but take care — some may stop your computer behaving as you wish. (Professional Edition only).

3. You can lock your XP workstation with two clicks of the mouse. Create a new shortcut on your desktop using a right mouse click, and enter ‘rundll32.exe user32.dll,LockWorkStation’ in the location field. Give the shortcut a name you like. That’s it — just double click on it and your computer will be locked. And if that’s not easy enough, Windows key + L will do the same.

Speed up your internet by 20%

Microsoft reserves 20% of your available bandwidth for their own
purposes like Windows Updates and interrogating your PC etc

You can get it back:

Click Start then Run and type "gpedit.msc" without quotes.This opens
the group policy editor. Then go to:
Local Computer Policy
then Computer Configuration
then Administrative Templates then Network then QOS Packet Scheduler
and then to Limit Reservable Bandwidth.


Double click on Limit Reservable bandwidth. It will say it is not
configured, but the truth is under the 'Explain' tab i.e."By default,
the Packet Scheduler limits the system to 20 percent of the bandwidth
of a connection, but you can use this setting to override the default.

So the trick is to ENABLE reservable bandwidth, then set it to ZERO.
This will allow the system to reserve nothing, rather than the default
20%.It works on Win 2000 as well.

Find ip address of the sender of a mail in Gmail, Yahoo and Hotmail

When you receive an email, you receive more than just the message. The email comes with headers that carry important information that can tell where the email was sent from and possibly who sent it. For that, you would need to find the IP address of the sender. The tutorial below can help you find the IP address of the sender. Note that this will not work if the sender uses anonymous proxy servers.
